Tixati 1.97

August 20, 2014

Tixati version 1.97 has been released. This is a maintenance release that contains many important fixes and several other minor improvements.

DHT Overhaul

- significantly faster DHT search speed

- vastly better protection against DoS and Clone/Flood attacks

- new incoming transaction soft ratelimiting system, to keep overall DHT traffic low under severe network conditions

- better cross-table high network concentration detection heuristics

- IPv4/6 cross-protocol bootstrapping improvements, better compatibility with Teredo systems

Transfers

- overhauled PEX (peer exchange) caching system

- increased maximum metadata size to accommodate extremely large torrents

- sparse file allocation is now the default method on filesystems that support it

- loosened file last-modified time matching rules (in an attempt to stop some reported problems with NAS units)

- eliminated a pause after clicking the Add button in some XP systems

- failing tracker will not fallback to unannounced mode while transfer is in running mode

- minor tracker protocol compatibility adjustments

- no downloading while checking during initialization phase

- fixed a crash in the preload window when Apply To All is checked and Skip Queue is selected

Channels

- overhauled connection certificate caching system for more reliable connections

- using alternate threading strategy for channel stream piece decoding (eliminates a Win7-only handle leak caused by a faulty 3rd party POSIX threading library)

- stream titles show in chat via /streamtitles option

- option to randomize selected stream playlist items

- short duration ts/mp3 files are streamed more smoothly

- fixed several other minor bugs with stream title passthrough to media player

- version column in connections view

- channel-list search IP concentration limits loosened

- several minor protocol tweaks

- channel search function minor fixes

Elsewhere

- fixed problems with POSIX threading library on Win7 platforms (handle leak)

- fixed problems with system suspend/resume on Win7 platforms

- improved SSDP and SLRD local peer discovery port-bind error handling

- minor UPC protocol adjustments

- minor fixes in UPC socket diagnostic charts

- Linux system suspend inhibition is now more reliable

- fixed minor problems in XP systems with saving config files in too large of chunks

- better handling of URLs containing # symbol (in RSS and other places HTTP is used)

- updated IP-Country database

Future/Soon/Next

- eliminate usage of file last-modified times to trigger checking (will instead keep block/file level hashes and use dynamic checking)

- overhaul of transfer multi-file management logic

- further investigation of some Win8 kernel panic problems (we did not observe problems on any of our Win8 systems, and are still trying to track this down)

- replacement of the .torrent auto-load system with something more reliable than the Windows file change notification API

- RSS auto-load / auto-start problems (this has also been difficult to recreate on our systems)

- a report of a Scheduler freezing problem

- overall framework upgrade to a leaner C++11 based system

More updates are being worked on. Thanks for using Tixati!
